| 中文摘要:U 盘的广泛使用为计算机之间交换数据提供了极大的方便, 但是在使用U 盘的同时也存在着U 盘可以未经允许而随意地读取的问题。针对这一问题, 现有的技术手段主要通过软硬件加密的方式解决, 但仍存在兼容性低、操作过程复杂、可移植性低等问题。为了解决这一问题, 提出了一个基于单板计算机的U 盘加密系统。该系统的设计以运行Linux 操作系统的单板计算机为基本框架, 采用了Linux 统一密钥设置(LUKS) 加密规范, 按照高级加密标准(AES) 为U 盘上数据提供加密保护; 通过媒体传输协议(MTP) 为计算机提供安全的连接, 为整套系统对计算机的连接提供极佳的兼容性。实验结果表明, 该U 盘加密系统可以为所有兼容USB 大容量存储设备的U 盘提供加密功能, 也兼容Windows 和Linux 等常见操作系统, 在确保安全性的同时具有极佳的通用性。 |

| Abstract:The extensive utilization of USB flash drives has bestowed significant convenience upon the inter-computer exchange of data. Nonetheless, concomitant with this convenience is the potential issue of unauthorized data retrieval from USB drives. In response to this issue, existing technical means mainly solve it through software and hardware encryption, but there are still problems such as low
compatibility, complex operation process, and low portability. To address this concern, a USB drive encryption system is proposed, based on a single-board computer platform. The foundational system involves the operation of a single-board computer running the Linux operating system. Within this system, the Linux unified key setup (LUKS) encryption protocol is employed, facilitating the encryption of data on USB drives through the implementation of the advanced encryption standard (AES). Secure computer connectivity is established through the utilization of the media transfer protocol (MTP), thereby conferring exceptional compatibility upon the entire system. Empirical results attest to the efficacy of this USB drive encryption system in furnishing encryption functionality to the entirety
of USB drives compatible with USB high-capacity storage devices. Remarkably, this system harmonizes seamlessly with prevalent operating systems, encompassing Windows and Linux, thereby simultaneously ensuring data security and engendering a commendable universality. |
